• Visual Studio 2008 (Pre-release) Loaded event order reversed in RC1

  Hi all, I have installed RC1 and there seems to be a problem with the order of Loaded events: the Loaded event for the top container is fired before the Loaded event for children. I have reproduced the problem in this simple XBAP project: http://www.valil.com/TestLoadedEvent.zip If you run the project in debug mode, you'll see in the output: Page loaded Grid loaded already Grid loaded which means the page is loaded before the grid. Yes, there was a recent change to fix another problem that caused this change in behavior. The order of the Loaded event shouldn't have changed; it is essentially broadcast through the element tree, so should fire on a parent before its children. But the IsLoaded property is updated th ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. What's difference between Express and Professional?

  I've installed the Express edition beta 1, but I have interesting to the Professional edition. I thought the Professional edition should have more classes than Express edition, but I've never seen any documentation to compare the class library of each edition. Could you tell me the differences of them, particularly about class library Or I'd be happy if I could find the reference manual of XNA Game Studio Professional on the net. Thanks, Hayashida EWSommer wrote: It looks to me like they intentionally removed useful functionality that was in DirectX so they could make you BUY something to write your own games that are more complex, so I'd start a trust fund if I were you...

• SQL Server Microsoft Visual Studio is busy

  I get this message in a balloon that pops up frequently when I am trying to work in the SSIS designer. For example, I get it when working in a DataFlow task, trying to open editors for the OleDb Source and Destination. Is anyone else getting this What could be the cause, it seems to get sluggish. Thanks. Hi there, same problem here. Since I use SSIS development in Visual Studio in combination with Vista, Visual Studio keeps being busy after executing larger SSIS packages.

• Software Development for Windows Vista Trying to derive a custom activity from another

  In the project we are wokring on we require a lot of almost identical activities. So instead of repeating all the common logic in every activity we created a "Base" activity and then tried deriving another activity from the BaseActivity. So we have something like… BaseActivity : SequenceActivity [HandleExternalActivity] Activity1 : BaseActivity [More Public Properties] Now I am running into problems after mapping the EventArgs that HandleExternalActivity’s interface requires in the BaseActivity. I get validation errors and/or already defined errors in the derived Activity class. Has anyone else tried doing someting like this I would really appreciate if someone could point me to th ...Show All

• Visual Studio Express Editions partial classes feature

  May I know how to turn off the partial class feature in Visual Studio 2005 (for express, and proffesional edition). Your avuable feedback is much appreciated. Thanks. IT is becuase MSBee is not support partial class feature in VS 2005. I failed to compile the program into .NET 1.1 version with MSBee.

• Visual C# time calculation

  Hi I've got a start time and duration. Both respresented as strings: string start = "00:01:36.3" string duration = "00:57:41.8" How would you calculate the end time (00:59:18.1) What's the easiest way Thanks Hi, you could try the following code: string start = "00:01:36.3" ; string duration = "00:57:41.8" ; DateTime startTime = DateTime .Parse(start); TimeSpan span = TimeSpan .Parse(duration); DateTime end = startTime.Add(span); Just ignore the date part in the variable (set to the current date).

• Visual Studio Team System Datadriven + test instance details

  I have two problems while doing my loadtest. 1. I have a datasource with 100 distinct user accounts, and I need to use them in load test. However, the system does not allow same user to be logged in twice in different web sessions at the same time. Once they logoff though, they can be reused. I need to simulate 50 users banging at the same time, so with 100 user base, I quickly run out of users in Unique mode. Is ther a way to tell test system to reuse accounts 2. While stress testing, some of the web tests fail (probably due to stress), but I only get the exception report in the load test. Is there a way to "digin" to specific iteration of the loadtest and see the output of that specific webtest (as I would get when I run ...Show All

• Visual C++ strcpy_s causes app shutdown

  I am updating some managed code to use the new string handling functions in VC8. I changed calls from strcpy to strcpy_s as shown in the code snippet below. The second call to strcpy_s causes the app to shutdown. No exception is thrown, no error code is returned. The app shuts down with exit code 0xC0000409 as the only clue. This is listed as a STATUS_STACK_BUFFER_OVERRUN in ntstatus.h. Of course it's telling me that it doesn't believe there is enough room in the buffer to accomodate the string. The error goes away if I change to strcat_s, or if I adjust the buffer size argument to take into account the length of the string that was previously copied in. Questions: How does strcpy_s know some of the buffer has been used Why ...Show All
